I study whether the effect of monetary policy has changed during 1990s and the zero bound of nominal interest rate may have some distortional effect on macroeconomic dynamics. In order to check the existence of structural change without any prior knowledge on break point and to be able to...

In this paper, I investigate the output composition of monetary policy transmission mechanism in Japan. It is usually thought that the investment channel, namely the process that a change in interest rate alters the cost of capital and therefore investment, is more predominant in Japan. Yet, in...

In this paper, I estimate the monetary business cycle model of the Japanese economy by the method advocated by Ireland (2002a), the max- imum likelihood estimation of the dynamic stochastic general equilibrium model in a state-space representation. The model estimated here includes the direct...

We consider the fiscal multiplier and spillover in an environment in which two countries are caught simultaneously in a liquidity trap. Using an optimizing two-country sticky price model, we show that the fiscal multiplier and spillover are contrary to those predicted in textbook economics. For...

How should monetary policy cooperation be designed when more than one country simultaneously faces zero lower bounds on nominal interest rates? To answer this question, we examine monetary policy cooperation with both optimal discretion and commitment policies in a two- country model. We reach...

Typically, when conducting econometric forecasting, estimation is carried out on a forecasting model that is built upon some assumed economic structure. However, such techniques cannot avoid running into the possibility of misspecification, which will occur should there be some error in the...

Three decades have passed since China dramatically opened up to the global market and began to catch up rapidly with leading economies. In this paper we discuss the effects of Chinafs opening-up and rapid growth on the welfare of both China and the rest of the world (ROW). We find that the...

In this paper, we investigate the relationship between real exchange rate dynamics and financial market imperfections. For this purpose, we first construct a New Open Economy Macroeconomics (NOEM) model that incorporates international staggered loan contracts as a simple form of the financial...

In this paper, we first construct a dynamic new Keynesian model that incorporates life-cycle behavior a la Gertler (1999), in order to study whether structural shocks to the economy have asymmetric effects on heterogeneous agents, namely workers and retirees. We also examine whether...
